Abstract:
Undergraduate students often struggle with Thermodynamics due to a
lack of hands-on experience with the devices and sensors discussed in
coursework. Traditional experimental setups—such as engine test benches and
HVAC systems—are prohibitively expensive and maintenance-intensive, limiting
student access and requiring large group work that can reduce individual
engagement. To address this issue, we developed and implemented a costeffective thermocouple calibration apparatus for use in undergraduate
Thermodynamics laboratories. The equipment utilizes affordable, readily
available components, enabling the creation of multiple identical setups within a
constrained budget. This allows students to work in smaller groups, increasing
interaction and individual learning opportunities. The apparatus supports
instruction in key Thermodynamics concepts, including temperature
measurement, sensible and latent heat, and the Seebeck effect. Results from
implementation show improved student comprehension and engagement. This
approach offers a scalable, practical solution for enhancing Thermodynamics
education, with potential applications across engineering curricula seeking to
improve experiential learning within limited resources.
